DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0156 AM CDT THU AUG 07 2025
VALID 071200Z - 081200Z
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE GREAT BASIN INTO
THE CENTRAL ROCKIES...
..SYNOPSIS
WITHIN THE BASE OF A ROBUST MIDLEVEL TROUGH MOVING ACROSS THE
NORTHERN ROCKIES, A BELT OF ENHANCED DEEP-LAYER WEST-SOUTHWESTERLY
FLOW WILL OVERSPREAD THE GREAT BASIN INTO THE CENTRAL ROCKIES -- TO
THE NORTH OF AN EXPANSIVE MIDLEVEL ANTICYCLONE CENTERED OVER THE
SOUTHERN ROCKIES.
..GREAT BASIN INTO THE CENTRAL ROCKIES
DIURNAL HEATING WILL YIELD DEEP BOUNDARY-LAYER MIXING INTO THE
ENHANCED FLOW ALOFT ACROSS THE GREAT BASIN INTO THE CENTRAL ROCKIES.
AS A RESULT, WIDESPREAD SINGLE-DIGIT TO LOWER TEENS RH WILL DEVELOP
AMID 20-25 MPH SUSTAINED WEST-SOUTHWESTERLY SURFACE WINDS. GIVEN
INCREASINGLY DRY/RECEPTIVE FUELS, ANOTHER DAY OF CRITICAL
FIRE-WEATHER CONDITIONS ARE EXPECTED.
..DRY THUNDERSTORMS - SOUTHWEST INTO THE CENTRAL ROCKIES
WITHIN A PLUME OF MIDLEVEL MOISTURE EXTENDING FROM THE SOUTHWEST
INTO THE CENTRAL ROCKIES, DIURNALLY DRIVEN HIGH-BASED THUNDERSTORMS
ARE EXPECTED -- WITH A FOCUS OVER THE HIGHER TERRAIN. THESE STORMS
WILL BE MOSTLY DRY, OWING TO INVERTED-V SOUNDINGS (0.50 TO 0.70 INCH
PW) -- POSING A RISK OF LIGHTNING-INDUCED IGNITIONS AND STRONG
OUTFLOW WINDS.
